Partial Shownotes:

Intro: Two weeks ago we gave an overview of IPv6. This week we take a look at some of the technical details for this protocol.

Mike: Gordon, a couple of weeks ago we discussed Ipv6 - can you give us a quick review - what's the difference between IPv4 and IPv6?The most obvious distinguishing feature of IPv6 is its use of much larger addresses.......

Mike: It's not just to have more addresses though, is it?It is important to remember that the decision to make the IPv6 address 128 bits in length was not so that every square inch of the Earth could have 4.3x1020 addresses......

Mike: Is there a specific RFC for IPv6?The IPv6 addressing architecture is described in RFC 2373.....

Mike: I know there is some basic terminology associated with IPv6. Can you describe Nodes and Interfaces as they apply to IPv6? A node is any device that implements IPv6.......

Mike: How about some more IPv6 terminology - can you discuss Links, Neighbors, Link MTUs, and Link Layer Addresses?A link is the medium over which IPv6 is carried......

Mike: Can you give a brief ouline in address syntax?For IPv6, the 128-bit address is divided along 16-bit boundaries.......

Mike: I know there are lost of zeros in IPv6 addresses - can you discribe zero compression notation?Some types of addresses contain long sequences of zeros......

Mike: IPv4 addresses use subnet masks - do IPv6 addresses?No - a subnet mask is not used for IPv6. Something called prefix length notation is supported.......

Mike: I know there are three basic types of IPv6 addresses - can you give a brief description of each?Unicast – packet sent to a particular interface.......

Mike: What about broadcasting?RFC 2373 does not define a broadcast address......

Mike: What about special addresses?The following are special IPv6 addresses......

Mike: How is DNS handled?Enhancements to the Domain Name System (DNS) for IPv6 are described in RFC 1886..... a

Mike: Can you discuss transition from IPv4 to IPv6?Mechanisms for transitioning from IPv4 to IPv6 are defined in RFC 1933.....

Mike: we've only touched on some of the IPv6 details - where can people get more information?I'm hoping to run a session at our summer conference July 28 - 31 in Austin, TX - we've currently got faculty fellowships available to cover the cost of the conference. See www.nctt.org for details.
